The present invention provides a glass fiber product having particles adhered to at least one fiber of the product, where the size and amount of particles is effective to reduce the tackiness of the glass fiber product and optionally effective to reduce interfilament bonding, and composition, and method for forming the same.

Fiber product coated with particles to adjust the friction of the coating and the interfilament bonding

An embodiment of a sizing composition for glass fibers comprises a starch, a nonionic lubricant, and a silane comprising at least one amine and at least one aryl or arylene group. Embodiments of fiber glass strands comprise at least one glass fiber at least partially coated with a sizing composition of the present invention. Embodiments of fiber glass strands can have tensile strengths that make the fiber glass strands desirable for certain processes, applications, and/or end uses.

Sizing compositions for glass fibers and sized fiber glass products

The present invention relates to terpene derivative compounds and rosins and sizing compositions comprising such compounds. Compounds of Formula (I) are disclosed in addition to rosins and sizing compositions comprising compounds of Formula (I). Fiber glass strands comprising a plurality of glass fibers at least partially coated with sizing compositions comprising compounds of Formula (I) are also disclosed.

Compounds, rosins, and sizing compositions

An aqueous sizing composition for at least partially coating a plurality of glass fibers can comprise at least one rosin, at least one coupling agent, and at least one lubricant. The rosin can be a chemically-modified rosin. A plurality of coupling agents can be included, including combinations of coupling agents that can provide for multi-resin compatibility and desirable fiber glass strand properties. An embodiment of a fiber glass strand at least partially coated with a sizing composition may have properties particularly suited for applications that do not utilize air jet weaving.

Sizing composition for glass fibers and sized fiber glass products

An aqueous starch-oil sizing composition is provided which produces improved processibility in woven and non-woven applications. The sizing has low viscosity starch, a lubricant which is a mixture of oil and wax where the wax is present in an amount of at least twice the oil, cationic lubricants, and a humectant. The size also includes an organo-functional silane coupling agent such as gamma-glycidoxypropyltrimethoxy silane which may be hydrolyzed. Emulsifiers, defoamers, and biocides may be present. Strands of glass fiber which have been treated with this size have generally shown a reduced tendency to shed the size from the strands, a reduction in the buildup of broken filaments or 'fuzz' on processing equipment and reduced strand breakage.

Starch-oil sizing for glass fibers

An aqueous chemical treating composition for glass fibers results in improved processing of the treated fibers in a bulking operation. The size has a starch-oil size with an imine-containing alkyl alkoxy silane. More particular, the size has one starch, one nonionic oil-type lubricant, one wax, one emulsifier for the oil, a nonionic wetting agent and a cationic lubricant and glycerine and the imine-containing silane and water where the silane is present in an amount of 0.1 to 10 weight percent of the solids.

Starch-oil treatment for glass fibers

Strands of starch-oil chemically treated glass fibers can have improved performance in high humidity environments. Such strands have a sole starch, film-former modifier which is a poly(oxypropylene) organic alcohol. Starch-oil sizings for treating glass fibers having polyethylene glycol are converted to improved starch-oil sizing compositions by substituting the poly(oxypropylene) organic alcohol for the polyethylene glycol. The strands of chemically treated glass fibers with improved high humidity performance are also made more lubricious by having a moisture-reduced residue of the starch-oil aqueous chemical treating composition with the poly(oxypropylene) organic alcohol. The more lubricious characteristic is effected by having present a starch mixture of a high amylose cationic starch and a highly crosslinked starch of approximately 50 percent amylose and wax in an amount less than the starch mixture but more than the oil and a cationic lubricant wetting agent and bacteriocide or fungicide. The moisture-reduced residue is present on the glass fibers in an amount of about 0.1 to about 2 weight percent LOI.
